Is there a difference in a 2.0L out of a bus as opposed to a 2.0L out of a 914? I was under the assumption that a bus engine had different heads. I don't know where I heard that. Maybe I just made that up.

There is a "bus" engine in my 914.

At least, it was a bus engine at one point. It was built into a 120Hp 2056, probably similar to what you have in mind. There are a few differences from 914 cases.

1) the dipstick is different for a bus. I carefully pulled the dipstick tube out and put in a 914 tube.

2) no taco plate oil temp sender. I scavenged one off another engine I had. The location is there, but the taco plate on the bus is just flat, it does not have the sender mounting location on it.

3) you can not use the oil temp sender off the 914. There is a big hunk of case in the way. You CAN use the short modern VDO sender, but then HAVE to use the 2 1/16 inch VDO oil temp gauge, not the big one from the 914. Other option is to hog out the case for the 914 sender to clear. I did not go that route.

4) Bus engine cases tended to warp around the registers. Mine has to be surfaced in order for the cylinders to sit in the case and be flush. This can happen to all T4 cases, but bus cases are especially prone as they were pushing big assed buses instead of little sports cars.

5) there is an oil gallery at the front of a bus case that needs to be plugged. I forget what its for in a bus. mine had a simple block off plate made from scrap aluminum.

I used the bus case as the journals were std. The 2.0 914 case I had was bored out and I was having a hard time finding bearings. Also, the oil galleries on my bus case had been tapped, and the 914 case still had freeze plugs.

If the oil galley is at the bottom of the case (cooling fan end of engine, opposite side from the oil cooler) then it's possibly for an oil fill. My Vanagon has an oil filler that is accessed by a door behind the license plate. That's where the dipstick is and the cap over the oil filler.
